N [Specification forming part of Letters Patent No; 104,534, da1ted June 21, 1870.

To all whom it mag/concern" N i Be it known that I, ROBERT AsHE, of Bosx NN ton, in the county of Suffolk and State of Mas- NN Usachusetts, have `invented certain Improvements in Channels for Boots.. and Shoes, of

fwhich the followingis al;Specification.:`

The nature of my invention consists in niaki N `ing two grooves upon the surface of thesole, yfor, the purposeof sewing on the upper leather "yor fabric of the shoe, the jcentral part of the .outer groove being out lower than the edge of the sole, thereby affording "sufficient channels i i'orsewing, and leaving theledgeoil the sole in various thicknesses of leather at any desirable thickness. y v N y N 1N In order to enable others skilled in the art `tonnake and use my inventionfl will proceed N` Figure 1` intheacconipanying drawing represents a sole, upon the shrfaceofwhich are groovesa a ct and b `ZI b, for-niing alift or rise, A A A, against the sholnlvders of which the stitch is closed. TheNcenterot' the groove a a Ny af isI deeper `than` the edge ofthe sole, asis better seen sectionalV `2; which the edge of the sole is left of the same thickness as the leather before the grooves were made.

Fig. 3 represents the same kindof grooves as Fig. 2, except that the edge of the sole is lthinned to a desirable thickness where and when the sole is too thick. N

Fig. 4 is a sectional view of the common channel where the edge oi' the sole, in order to obtain a sufficient channel, is shaved down thin, giving the appearance of a sole of but N little durability, especially7 when it is made of thin leather.

The utility of my said invention consists in makin g better shoulders on thin leather, against which the vstitch is closed, than the common channel affords, and rendering it easy to make the soles of boots and shoes appearof the same thickness and durability from varying thick.

ROBERT ASHE.
